The Murchison meteorite that fell on an Australian town in 1969 contains grains of stardust 7 billion years old, meaning the dust predates the Sun itself and is the oldest solid material ever held in a human hand
In 1969, a fireball broke over the Victorian town of Murchison and scattered carbon-rich stones across the paddocks. Inside them sat grains of silicon carbide that condensed in dying stars roughly 7 billion years ago — older than the Sun, older than the Earth, and the most ancient solid material ever held in a human hand.
